Living cells may generate electricity through the natural motion of their membranes. These fast electrical signals could play ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and out of cells.

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Researchers have uncovered a previously unrecognized role for immune cell surface sugars in driving inflammation in psoriasis. Scientists have refined how they understand the role of sugars called ...

Inside every living cell, tiny molecular machines are constantly in motion, shifting shapes, tugging on membranes and ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...
